Letters Patent No. 101,916, dated April 12, 1870.

IMPRAOVEMENT IN RESERVOIRS FOR COOKING-STYES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, ALBroN RANsoM, otthe city and county of Albany and State of New York, have invented a new and useful Improvementin Hot-water Tanks or Reservoirs for Cooking and other Stoves, and in other similar vessels; and I hereby declare the following to be a full and exact description of vthc same, reference being had to the accompanying Experience has demonstrated that water-tanks or.

hot-water reservoirs, sueltas have been attached to cooking-stoves, are not durable, owing to their liability to oxidize by the action of warm or hot water upon tle internal surface of the same.

To avoid this diiiiculty, such tanks or reservoirs have sometimes been galvanized on the inside, and sometimes they have been enameled and coated, without very great success. The galvanized surface would soon wear on, and the enameled surface would break and crack otf, leaving the under iron surface exposed to the action of the hot water, and it thus oxidizes, to the ruin ofthe tank.

To obviate these difficulties this improvement is made, which consists in making a compoundtank or reservoir in the manner following:

I first construct, of sheet-iron, wrought iron, or castiron, and I prefer cast-iron, an outside casing of the size and shape of the vessel, tank, or reservoir to be constructed,` This outside casing is designed as a means ofstrength and protection. Inext construct, of sheet-tin, or any other suitable metal sheet, as copper, zinc, brass, and suc-h' like, which may be the ordinary tin, or sheets speciallyprepared for the purpose by being tinned only upon theinside, an inside lining,`

fitting the same accurately to the inside of the iron casing so as to leave as little space between the lining andthe case as possible. Then, for the purpose ot' illing any possible spacewhich might exist between these surfaces, and for the purpose of facilitating the transmission of heat ii'om the outer case to the water within the tank, and for the purpose of preventing oxidation, I paint o r coat over the outer surface of the lining, and sometimes the inner surface of thecase, with any durable paint or material, preferring that which is `black or dark colored, for which purpose black-lead, or earth or rock paint, sometimes called mineral paint, is very suitable.

vThe tank 6r reservoir thus constructed is denominated Ransoms Improved Compound Hot-water Tank or Reservoir, consisting of the outside casing, of the inside tin lining, and of the uniting coat of paint or other suitable material.

When, in the construction of this compouudtank, I use, for lining, plates tinned only upon one side. 1f the lining is fit-ted sufficiently close to the outside casing, the uniting paint or coat may be omitted.

In adjusting the lining to the outer case, the top of the lining should be turned out so as to form a cap or flange, fitting closely over the top of the outer casing, to prevent the possibility of introducing water or steam between the surfaces ofthe casing and the lining.

This top cap is shown in the accompanying lig. 2.` in the drawings hereto attached and tbrming apart of this specification.

In the accompanying drawings- Figure 1 is a representation of thebody of the outer casing.

Figure 2 represents the lining of sheet-tin, and

Figure 3 represents the tank complete, with its cover on, and one of the iron lids raised up.

Having thus fully described the nature. and use of my said improvement, I will proceed to state how much of the same I cla-im as my own and desire to secure by Letters Patent.

I do not claim a hot-water tank or r \servoir, either enameled or galvanized, for reasons above set forth. Nor do I claim the simple tinning of the inside of an iron vessel, because that would not give the advantages arising from my compound reservoir, either in neatness of finish, strength, durability, or ease of re pair. ABy using my compound reservoir, whenever repair becomes necessary, the tin lining can be removed and a new one put in its place without taking the reservoir from the premises, and thus the expense and trouble ofrepair are but trifling.

What I do claim as my invent-ion, and desire to secure by Letters Patent, is y y 1. A compound hot-water tank or reservoir, constructed in the marmer and for the purposes above set forth and described.

2. The aforesaid described process or mode of coustructing hot-water tanks and other similar vessels, consisting of making the ,outer case of iron, sheet, wrought, or east, and the inner lining of sheet-tin, tiuned on one or both sides, or other suitable sheet metal, as above described, closely fitted together and painted or coated between adjoining surfaces, substantially as described. y
